Re: a bug report on info.el

[Richard M. Stallman]

    However, I think last two lines should be written like this:

              (append   (split-string path (regexp-quote path-separator)))
      (Info-default-dirs)))

    Otherwise, the last (Info-default-dirs) won't be appended to
    Info-directory-list.

You are supposed to end INFOPATH with a colon
if you want the defaults added at the end.
